Viewing a list of all fields available to customize a form
The "plain paper" and "pre-printed" views in the Customize window automatically display all of the fields that are incorporated into the basic design for each form. To display an alphabetical list of every data field that you can include on a form you want to customize, click the Add New Data Field/Column button on the left end of the toolbar in that form's Customize window. Use the Select From List window to select the fields you want to include in your custom form layout. (Forms you can customize)
